60 years of denial about Israel’s nuclear weapons program confronts a new reality

In early 1960, an American group of diplomats riding in an Israeli helicopter spotted a construction site in the Negev desert near the Dead Sea. The site was later revealed to be the Dimona nuclear facility, which became the birthplace of Israel's atomic arsenal. It took several months for US Ambassador Ogden Reid to demand a meeting with Addy Cohen, the Finance Ministry representative, after US intelligence deciphered the true nature of the site.

Reputedly, Cohen initially treated the situation lightly, believing the reactor could potentially be used for weapons. Five years later, US nuclear officials discovered a significant amount of weapons-grade enriched uranium missing from a Pennsylvania plant, which some officials believe may have been diverted for Israel's program.

Despite this, both the US and Israel have maintained a policy of ambiguity regarding Israel's nuclear arsenal, neither formally confirming nor denying its existence. This policy has helped both nations avoid international scrutiny and maintain a public stance against other countries developing nuclear weapons. However, as other regional powers advance their nuclear programs, the US and Israel may face increasing pressure to acknowledge Israel's nuclear capabilities.

Transparency could potentially undermine the US's argument against other nations joining the nuclear club and may result in economic sanctions or arms sale embargoes. The Israeli Embassy in Washington, DC, has not commented on the matter, referring inquiries to the prime minister's office.
